All non-plated holes get a pad size that is much smaller than the hole size, thus the negative number.

It's simply a feature that allows you to see the annular ring value on Plated Through Holes.

But then it doesn't really make sense when the program automatically fills in a negative value for that option. And I still don't see when I would want to use this, all that's needed to define a hole is the drill diameter and the pad diameter, this third parameter is just confusing and it's not at all clear what it's purpose is.]]> Thu, 10 Nov 2016 00:22:29 +0000 https://www.PCBLibraries.com/forum/size-over-hole_topic2002_post8258.html#8258 <![CDATA[Size Over Hole : The Size over the Hole is exactly...]]> https://www.PCBLibraries.com/forum/size-over-hole_topic2002_post8253.html#8253 Author: Tom H

The Size over the Hole is exactly that.

Example: you have a 1.10 pad with a 0.70 hole = 0.40 Size over the Hole

You have the choice of changing the Pad Size or the Size over the Hole value.

Maybe a stupid question but, what is the meaning of the option "Size over hole"?

If a define a through hole padstack with a diameter of 3mm and then check the padstack manager, the parameters show "Size/XY" 1mm and "Size Over Hole Y" -2mm.
